Clang has custom handling of --no-demangle, where it is removed from the input -Wl and -Xlinker options, and readded specifically by the drivers where it's known to be supported. Both ld.bfd and lld support the --no-demangle option. This handles the option in the same way as in ToolChains/Gnu.cpp. Differential Revision: https://reviews.llvm.org/D114064
